如何设置SmartFilter entitySet

Question

当我试图过滤一些东西(SmartFilter)时，我得到了一个404错误，检查我的有效负载，我发现其中没有实体：

GET null/$count?$filter=startswith(undefined,22) HTTP/1.1

这个可以用

GET RfcSearchRequisitionsSet?$skip=0&$top=100&$filter=(Banfn%20eq%20%2722%27)&$select=Bsart%2cBanfn%2cBnfpo%2cWerks HTTP/1.1

XML

                <smartFilterBar:SmartFilterBar id="smartFilterBar"
                    entityType="RfcSearchRequisitions">
                    <smartFilterBar:controlConfiguration>
                        <smartFilterBar:ControlConfiguration
                            key="Banfn" index="1" groupId="_BASIC" width="300px"
                            visibleInAdvancedArea="true">

                        </smartFilterBar:ControlConfiguration>
                    </smartFilterBar:controlConfiguration>
                </smartFilterBar:SmartFilterBar>
                <smartTable:SmartTable id="smartTable"
                    entitySet="RfcSearchRequisitionsSet" smartFilterId="smartFilterBar"...>

注解

<Annotation Term="com.sap.vocabularies.UI.v1.LineItem">
<Collection>
<Record Type="com.sap.vocabularies.UI.v1.DataFieldForAnnotation">
<PropertyValue Property="Label" String="DocType"/>
<PropertyValue Property="Target" AnnotationPath="BSART"/>
</Record>

Answer 1

问题在于注释，它们应该是这样的：

<Record Type="com.sap.vocabularies.UI.v1.DataField">
    <PropertyValue Property="Label" String="DateCreated"/>
     <PropertyValue Property="Value" Path="Erdat"/>
</Record>

请将以下代码片段复制到您的控制器中，并将该方法添加到SmartTable XML中的事件"beforeRebindTable“中。喜欢: beforeRebindTable="handleBeforeRebindTable“

handleBeforeRebindTable: function(oEvent) {
        var mBindingParams = oEvent.getParameter("bindingParams"),
            aCustomFilters = [],
            sFilterValue = 22;  // it's an example, use your filter value

        // Getting filter parameters value
        if (sFilterValue ) {
            aCustomFilters.push(new sap.ui.model.Filter("Banfn", sap.ui.model.FilterOperator.StartsWith, sFilterValue ));
        }

            var oOwnMultiFilter = new sap.ui.model.Filter(aCustomFilters, true);
            if (mBindingParams.filters[0] && mBindingParams.filters[0].aFilters) {
                var oSmartTableMultiFilter = mBindingParams.filters[0];
                // if an internal multi-filter exists of your smart table then combine custom multi-filters and internal multi-filters with an AND
                mBindingParams.filters[0] = new sap.ui.model.Filter([oSmartTableMultiFilter, oOwnMultiFilter], true);
            } else {
                mBindingParams.filters.push(oOwnMultiFilter);
            }

    },
